Functions

LOUDER AND CLEARER AUDIO

Industry-leading audio quality through AI-based voice enhancement with deep learning ability that can accurately extract voice from background noise in real time. The howling suppression prevents feedback between two radios in the same vehicle, ensuring clear and uninterrupted communication on the move.

MULTI-SYSTEM FLEXIBILITY

The HM682 mobile radios can be deployed in Analog and Digital Conventional, DMR Tier II, and optional Hytera XPT Trunking (multi-site with license), and support Roaming between repeater sites.

GREATER CALLING FLEXIBILITY

Supports Individual Calls (radio to radio, radio to dispatcher), Group Calls (one radio to many, dispatcher to many), and All Call (broadcast call to all radios, transmit only).

IMPROVED WORKER SAFETY

The HM682 is designed for worker safety with an easy access emergency call button. Lone Worker prompts the user to press a key at preset intervals to indicate they are safe. Optional Priority Interrupt (with license) allows a dispatcher to interrupt existing calls with important emergency information, and a dispatcher can remotely enable and disable radios.

ANALOG OR DIGITAL MODE

The HM682 radios can operate in either analog or digital mode, which is the ideal solution for migrating from analog to digital with minimal disruption and investment.

CLARITY TRANSMISSION

Provides a wireless data path between remote network devices and a central network management station. HM682 mobile radios function as compact gateway devices and provide wireless channels that transparently transmit data without modification, and can be deployed in a variety of monitoring and control processes.

DURABLE AND RUGGED

IP54 compliant for water and dust ingress, and MIL-STD- 810 G for shock and humidity. The 10pinaviation connector for the handheld microphone is tight and secure, and coil cable has excellent stretching ability for long service life.

ENHANCED GPS LOCATION TRACKING

HM682 models that support GPS report current location information to other radios, the dispatcher, or third-party applications in real time, enhancing the efficiency of visualized dispatch applications. GPS data is transmitted during voice calls for immediate location targeting, and GPS data is compressed to increase channel capacity and reduce hardware cost.

GREATER RANGE

With high RX sensitivity, the HM682 delivers clear and dependable communication even in areas where the signal is unstable or weak.

HIGHER SECURITY

Supports Digital End-to-End Encryption for voice and data. Optional advanced AES 2456 bit encryption is also available (optional with a license).

FRONT PANEL CONTROLS AND LCD DISPLAY

The front panel features tactile buttons and piano keys for easy operation, and the LCD display is readable even in the dark or direct sunlight.

BUILT-IN BLUETOOTH

HM682 models that feature Bluetooth support audio handset accessories to improve safety and productivity during in-vehicle communications

BACK-TO-BACK

The HM682 can be deployed Back-to-Back with an accessory cable to enable communication between analog and digital radios, or radios with different frequencies.
